This paper is to explore considerations in authority control to accommodate LRM nomen entities through the literature reviews, the analysis of RDA rules, and the opinion survey of domestic catalog experts. As a result, for authority control, considerations were proposed in the aspect of nomen's attribute elements, catalog description, and MARC authority format. First, it is necessary to describe in as much detail as possible the category, the scheme, intended audience, the context of use, the reference source, the language, the script, the script conversion as the attributes of the nomen with the status of identification, note, and indifferentiated name indicators added in RDA. Second, the description method of attribute elements and relational elements of nomen can be unstructured, structured, identifier, and IRI as suggested in RDA, and vocabulary encoding scheme (VES) and string encoding scheme (SES) should be written for structured description, Also, cataloging rules for structuring authorized access points and preferred names/title should be established. Third, an additional expansion plan based on Maxwell's expansion (draft) was proposed in order to prepare the MARC 21 authority format to reflect the LRM nomen. (1) The attribute must be described in 4XX and 5XX so that the attribute can be entered for each nomen, and the attributes of the nomen to be described in 1XX, 5XX and 4XX are presented separately. (2) In order to describe the nomen category, language, script, script conversion, context of use, and date of usage as a nomen attribute, field and subfield in MARC 21 must be added. Accordingly, it was proposed to expand the subfield of 368, 381, and 377, and to add fields to describe the context of use and date of usage. The considerations in authority control for the LRM nomen proposed in this paper will be the basis for establishing an authority control plan that reflects LRM in Korea.

ALC(Asyncronous Layered Coding)는 LCT(Layered Coding Transport)기반의 폭넓은 확장성과 다양한 전송속도로 신뢰성 있는 멀티캐스트 전송을 주 목적으로 한다. ALC는 다른 RMT 프로토콜과는 달리 재전송을 하지 않고 receiver-driven 형태의 혼잡제어를 하기 때문에 신뢰성을 제공하기 위해 FEC(Forward Error Correction) 스킴를 이용한다. 본 논문은 신뢰적인 멀티캐스트 전송 프로토콜을 위해 ALC와 FEC 스킴 중 하나인 LDPC 코드를 이용하여 구현한다. 인코딩 비율(Encoding ratio)에 따라 일정 수준 이상의 복구 성공 확율에 대해 최대 허용 가능한 패킷 손실률을 측정하여 신뢰치를 측정한다. 마지막으로 일대다의 파일 전송 시, TCP와 비교하여 본 구현물의 유연성과 효율성에 대해 분석 및 평가한다.

볼륨 데이터는 시뮬레이션 통해 생성되거나 고성능 측정 장비를 이용해 측정된 값으로 구성되는 고차원 데이터의 한 형태로서 다양한 자연과학과 공학분야에서 폭넓게 활용되고 있다. 최근에는 각 분야에서 생성되는 계산 데이터의 용량이 점점 더 증가하고 있기 때문에 이런 대용량의 볼륨 데이터를 효과적으로 처리하기 위한 기법들에 관한 연구가 수행되고 있으며, 특히 대용량 볼륨 데이터 압축 기법에 대한 필요성이 증가하고 있다. 본 논문에서는 Daubechies 웨이블릿 변환과 zerobit 인코딩 스킴을 응용한 새로운 볼륨 데이터 압축 기법을 제안한다. 이 방법은 기존의 압축 방법에 비해 복원 데이터의 손실이 낮기 때문에 정밀한 영상을 요구하는 대용량 데이터 압축에 유용하게 사용될 수 있다.

A case study bas been conducted to explore design activities of four expert designers through protocol analysis, We examined relations among design information, process patterns and solution qualities with two complementary coding schemes based on design contents and design process, Relation between personal creativity modes and design activities has been examined as well. Regarding design process, an adequate distribution of activities in process may be necessary to bring out a good solution. It seemed that the more design contents about context, external knowledge, and general feature are used, the more unique design concepts are made. Regarding personal creativity modes, not much of differences in that design activity were observed while only a few relations between designer's personality and design activity were observed. The fact that the designers participated are all experienced designers could explain this. Investigation on the differences between novice designers and expert designer reflected in protocol data based on design information and design process coding scheme is to be done. Also, how personal process patterns observed through this protocol analysis can be utilized in composing design team.

The objective of this research is to discover the rule of gameplay related to the task interdependence to analyse the behavior pattern of social gameplay. Previous literatures related to the gameplay were reviewed and game which was suitable for the gameplay of the task interdependence was selected. A party-play includes a team of five people in the experiment during the gameplay with think-aloud method and video/audio data about action protocol and verbal report were collected. The video observation and protocol analysis were conducted to analyse data. The objective coding scheme were developed from consolidated sequence model task analysis. The player's behavior was analysed. The result was revealed that four rules and four modified rules were included into the total eight behavior pattern. A behavior graph integrated with five gameplay was written. The excellent cooperative spot and error and failure place could be identified. The social gameplay behavior graph is expected to be the key practical design guideline on whether the level design and balance design are proper.

With the increase of the number of Internet users, various methodologies have been proposed for the effective design of web page. However, the prior methodologies have focused only on the functional aspect of web page while ignoring the emotional aspects of web pages. This paper focuses on the emotional design of home pages and aims to provide a methodology to design a web page suitable for goal emotions. In order to achieve the main purpose, we have conducted three related studies. First, we have identified basic emotional dimensions representing various feeling users have from web pages as a pool of emotional adjectives. Second, we have identified key design elements related to the emotion by observing the design process of expert designers. Third, we examined the causal relation between the perceived emotion and designed elements. The results indicate that some design elements are more effective to produce certain feeling than others. This paper ends with limitations and implications of the study results.

Visible light communication technology is being studied and developed in various ways due to advantages such as high transmission speed, excellent positioning and higher security. However, existing visible light communication systems have difficulties in entering the market because they use special transmitters and receivers. We will overcome the difficulty if we develope a VLC system that uses a conventional LED light as a transmitter and a smartphone camera as a receiver. What matters is that LED lights include a scatter filter to prevent glareness for human eyes, but the existing VLC(Visual Light Communication) method can not be applied. In this paper, we propose a method to encode data with On / Off patterns of LEDs in the lighting with $M{\times}N$ LEDs. We defined parameters like L-off-able and K-seperated to facilitate the recognition of On / Off patterns in the diffused Lights. We conducted experiments using an LED lighting and smart phones to determine the parameter values. Also, the maximum transmission rate of our encoding technique is mathematically presented. Our encoding scheme can be applied to indoor and outdoor positioning applications or settlement of commercial transactions.

This study examines the literature regarding teacher-child interaction in the classroom, aiming to find ways to support child-care teachers in improving the quality of teacher-child interaction. The study selected studies exploring teacher-education programs that aim to support child-care teachers in interacting with their children in the classroom in a quality manner. The selected studies were analyzed, by focusing on how the study proposes ways to support child-care teachers in interacting with their children in a quality manner. The results of previous studies are as follows: 1) the literature tends to focus on teachers' language interaction with their children in the classroom; 2) the literature tends to apply a variety of observation tools (or coding schemes) to measure teacher-child interaction in child-care settings; 3) the literature prefers individualized approaches such as mentoring or consulting as ways of supporting child-care teachers in interacting with their children in a quality manner; and 4) the literature aims in general to improve teachers' self-reflection skills.
